Its main function is to be a flexible accessory of various lifting machinery, so that the hook can move up and down on the wire rope to achieve the purpose of lifting objects. Steel wire can also be used for tensioning. The high-voltage conductors on high-speed trains are suspended on the rails with steel wire ropes, etc. Testing the tensile performance of steel wire is an indispensable step after the production of steel wire is completed. The tensile test device can be used to perform tensile tests on steel wires of various specifications to know whether their tensile strength meets the standard or what range of use their tensile performance should meet, thereby ensuring that the steel wire can be used safely and stably in actual use and is not prone to breakage.
